If you find the right person, it can actually be a lot more fun. I've watched quite a few Let's Plays of older games, some of which I never got the chance to play, or that I don't have the energy to play. Some people are funny, some informative, and often both. If you look at it like a commentary track from a dedicated fan, that might help. Then again, Mystery Science Theater 3000 was one of my favorite shows back in the day. However, perhaps you haven't found the right LPer for your personal tastes. Just a thought.

That's fair, but from my own experience doing pixel art, this is something that looks a lot more inspired by Legend Of Dungeon, Superbrothers and other indie games with a pixel art style, as opposed to games like Monkey Island and Castlevania.

If you do pixel art yourself then obviously you will differentiate more than a layman. To me EVERY pixel art is reminiscent of old adventure games because that is about the only source I know it from. Same goes for a lot of other people I imagine. And it's not crazy to associate pixel art with a time when it was the most advanced and therefore dominant form of computer graphics that we had.

I like the pixel art here, but the way the horizon is in line with the ridge the characters are standing on is a bit visually confusing. It would probably work much better if the ridge were moved higher.
